I do make money trading forex. Firstly, why am I more admirable than the guy who opened an off licence just around the corner and is doing so well that he is opening two additional ones in two separate locations in London? I talk to him and I know I can't do what he has been doing to make the business work. And I am sure he can't do what I am doing. What is the big deal about trading? If you are undercapitalised, you will probably fail, but then if the guy is undercapitalised he will fail too. If you are afraid of losing so don't let your profits run long enough and grab tiny gains all the time, for example, you will fail. If the guy is afraid of the risk of his business failing, he will never do what he needs to do. If you don't like working hard you will fail. The same is true for him.
I know what he is doing and I can follow him and watch what he is doing, but I don't think I can, or want to, do what he does. It is the same in trading. I can tell you exactly what I do or you can come and watch me, but I am sure in the vast majority of cases, you will fail. It is then pretty silly to think it cannot be done.
Do people make money trading? Of course they do. Is it hard? Yes, but so is any other business where hard work, commitment, courage, patience and the willingness to lose are required.
All the best.
